UNITED STATES JOHN H. FRY, OF GRAND RAPIDS, MICHIGAN.

LAWN-SPRINKLER.

SPECIF forming part of Letters Patent No. 572,000, dated November 24, 1896.

A li ation fil d August 27, 1895. Serial No. 560,680. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. FRY, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new andusefulImprovements inLawn-Sprinklers, of which the following is a specification.

This invention relates to lawn-sprinklers or hose-nozzles, and has for its object to provide novel, simple, efficient, and economical means whereby it is possible to spread the stream issuing from the mouth of the nozzle and spray the water to a greater or less extent without stopping the flow of the water to or interrupting the discharge of the water from the nozzle.

Figure 1 shows a longitudinal sectional view of a nozzle containing my spraying device on a line through the central opening of the nozzle. Fig. 2 shows a front elevation or front view of the spraying device and nozzle, with the nozzle raised at an angle of about forty-five degrees in order to show the hood and the relative position of the spraying device and the opening.

Similar letters refer to similar parts throughout both views.

A represents the nozzle proper, provided with an opening 13, through which the water is discharged.

0 represents a hood at the front end of the nozzle, which is intended to prevent the water from rising too high or spreading too wide. The hood is open or cut away at one side.

In the example of my invention shown in the drawings I have shown four fingers, (indicated by E, F, G, and The sprayingfingers are all mounted on a single bolt J. This bolt may be screw-threaded and engage with a screw-thread in the nozzle, or it may be permanently attached to the nozzle and provided with a nut for retaining the spraying-fingers in place. Upon this bolt the arms are adapted to rotate. Vhen it is desirable to use the nozzle without the operation of the spraying-fingers, the fingers can be turned so that the opening B will be between two of the fingers and the Water will then pass ofi freely without coming in contact with the fingers.

\Vhen it is desired to use my invention for sprinkling streets, where the stream should be but little spread, I use the narr w finger E. If I desire to spread it mor rise the finger H, and if I desire to obta a q eatest amount of spreading surface, in oruer to carry the water to a finer spray, I use thebroader finger G. It will be noted that a less number and a greater number than four fingers might be used in this rotary spraying device, but I deem four preferable, for the reason that there is greater room between the fingers for the round stream than there would be if a larger number of fingers were used, and the use of the four fingers of different sizes or widths will allow of the use of a greater variety of sprays than if a less number of fingers were used.

In order that the water when striking the fingers will not flow backward or will not be thrown backward, so as to drip from the spraying-fingers, I prefer to make them angular or rounded on their upper surface. I have found by actual experiment that the fiat upper surface to the spraying-finger was not desirable. The water striking with considerable force against the flat surface has a tend- In the use of an ordinary nozzle when itis desired to spread the water issuing therefrom the person holding the nozzle places a finger, usually the forefinger, over the end of' the nozzle, and according to the pressure applied the stream of water is more or less spread. By my invention it is unnecessary to place the finger over the nozzle, while the pivoted fingers of different width secure the necessary changes in the spread of the stream in a very efiective manner.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

The combination with a nozzle, of a pivot side of said nozzle to permit an unobstructed flow of water from the nozzle between them, substantially as described.

In witness whereof I have hereunto set my I 5 hand and seal in the presence of two witnesses.
